Check Out My New SDRplay RSPdx Software-Defined Radio Receiver – Live!
My new SDRplay RSPdx software-defined radio receiver is live, via http://www.sdrspace.com/Version-3, using the SDR Console software (Version 3).
The receivers are online whenever I am not transmitting and when there are no local thunderstorms.
Antenna Port A is a wire antenna (100′), while Antenna Port B is a VHF/UHF discone. Both have an AM Broadcast band reject filter, reducing local AM Broadcast signals by about 30 to 40 dB. I need to use these because the very close KLIN transmitting tower is just miles away and those signals overwhelm the receiver. When I use the signal filters, the local AM Broadcasting signals no longer overwhelm the receiver.
Let me know what you think. Enjoy!
To use my receiver:
Install the latest version of SDR-Console which can be downloaded from https://www.sdr-radio.com/download
Install SDR Console according to the directions given. Once you have the software installed, you will want to add my server.
It takes a little to get familiar with the software, but there are online FAQs on how to begin.
My server is known as, ‘0 NW7US‘ — it will be online when I am not using my antenna systems for transmitting. It will be offline during thunderstorms, or during times when I must use the systems for transmitting.
Software-defined radio is a great way to hear all sorts of communications, from local AM broadcast stations, FM stations, VHF Air Traffic, to shortwave radio stations including amateur radio HF communications.

Everything Ham radio podcast Ep 93 – NASA On The Air(NOTA)
I’m sure that you have heard of NPOTA, National Parks On The Air, and SOTA, Summits On The Air, and probably even POTA, Parks On The Air, The US program for the World Wide Flora and Fauna, but have you heard of the latest event that starts on Sunday, Dec 11, 2017?
Starting at 0000 UTC time on December 11, 2017 the new year long event celebrating multiple anniversaries for the NASA program will start. It is called NOTA or NASA On The Air.
With several NASA clubs doing several special event stations of the coming year, they decided to make a year long event where you, as the end user, can contact the stations to earn points through the year. You can even gets points during other events like Winter Field Day, the ARRL Field Day and others.
Losten to my latest podcast episode where I talk with Rob Suggs about it:
ARISS 20th Anniversary SSTV
The 20 year history of ARISS was displayed through a collection of 12 images highlighting the accomplishments of the project over the last two decades.
As the ISS has orbited the world it has been transmitting the SSTV signals using FM on the usual downlink of 145.800 MHz, here at my QTH in the UK the passes have occurred late at night into the early morning, averaging 3 - 4 reasonable passes each day.
The signal has been very strong and so some excellent low noise images have been received by many people using just modest equipment. While not the greatest technical achievement in the world it nonetheless generates much needed interest in ARISS and amateur space communication.
My own system consisted of the Yaesu FT-857D and MMSSTV running on the shack PC and was left on automatic receive (I was tucked up in bed) and managed to get decent copies of all the images.
Image 8 reminded me of the fun I had back in 2011-2012 of receiving the ARRISAT-1 and was one of the key things that convinced me to finally get off my backside and actually get licensed, even if it took me another 12 months and to this day haven't really cracked satellites myself! My previous blog posts on that can be found at http://nerdsville.blogspot.co.uk/search/label/arissat-1
Here are the best of my images, for a full description of what each one depicts visit http://ariss-sstv.blogspot.co.uk/2017/07/anniversary-image-descriptions.html

Hamvention Is Here – ETH069
With Hamvention already on top of us, I figured I’d throw my two cents worth into the mix with everybody else’s. In this episode of the Everything Ham Radio Podcast, we talk about some of the interesting things that are going to be going on at this years Hamvention at it’s new location in Xenia, OH.
DARA teamed up with The Miami Valley Mesh Alliance (MVMA) to setup a Mesh network on channel -2 at 10 MHz bandwidth. The SSID is AREDN-10-v3.
We talk about all of my fellow podcasters/youtubers that are there and what they have going on and where they are at.
Lastly, we discussed some of the interesting forum topics that are going on during the weekend. To listen to the episode as well as check out all the links and further information on the topic, check out the show notes at:
Sending Christmas Greetings to the ISS
As luck would have much of the UK had a crystal clear sky and I even managed to get my 80 plus year old Mother-in-law out in the garden to watch the spectacle. She was impressed and it was great to overhear lots of excited children coming out in the nearby homes to watch Santa as he flew overhead.
Back in October 2013 after becoming a newly licensed radio amateur I managed to send APRS packets to the International Space Station which were digipeated and received back on earth by other operators. Back then I used a lowly Baofeng UV5R handheld and I decided to repeat the exercise this time using the FT857D (this time running around 20W) to talk to Santa!
The computer I used back then has been decommissioned so on the laptop I installed the UISS program from ON6MU which makes easy work of APRS to the ISS and instead of the cumbersome AGWPE I used the excellent soundcard modem from UZ7HO.
I attempted to send a message on the pass at 15:43 but failed completely, discovering I'd got my soundcard incorrectly set up. I corrected this and left the autobeacon mode running in UISS during the Santa pass and checking back much later could clearly see I'd sent and had a message repeated back from the ISS.
Checking the ariss website (www.ariss.net) I could see the repeated message had been received by another station and my position was showing up on the map (M0NRD)
I have successfully done it again today on Christmas Day! As the raw packets below confirm.
M0NRD>CQ,RS0ISS*,qAR,DM2RM:73' Happy Christmas from Andrew IO93OB
M0NRD>CQ,RS0ISS*,qAR,MB7USS:=5304.08N/00048.47W-73' Happy Christmas from Andrew
M0NRD>CQ,RS0ISS*,qAR,HG8GL-6:73' Happy Christmas from Andrew IO93OB
It was a nice achievement and another nice Christmas present was achieved early this morning while running WSPR on 40m, managing to get received in New Zealand
Anyway enjoy the rest of the festive season and I wish you all the best in 2015
